CENTRIFUGAL MACHINE.

SPECIFICATION forming part of Letters Patent No. 5,536, dated August 7,1900.

Application filed March 8, 1900- Serial No. 7,787: (No model.)

To all whom it may concern.-

Be it known that I, DAVID WILLOX, a citizen of the United Kingdom ofGreat Britainand Ireland, residing at 48 Burgher Street, Parkhead,Glasgow, Scotland, have invented certain new and useful Improvements inor Relating to Centrifugal Machines, (for which application for patenthas been made in Great Britain, No. 24,017, dated December 2, 1899,) ofwhich the following is a specification.

This invention relates to centrifugal machines, and more especially tosuch as are used for drying clothes or fabrics; and it has for itsobject to provide means whereby risk of accident occasioned by throwingin articles to be dried while the centrifugal basket is in motion or bycontact with it may be obviated.

The accompanying drawings illustrate an under-driven centrifugalmachine, showing my invention applied thereto, Figure 1 being anelevation with the cover of the machine closed, Fig. 2 a plan of thesame, and Fig. 3 an elevation showing the cover open. Fig. 4 is averticalsection, and Fig. 5 a horizontal section, of the improvedcentrifugal machine, showing the rotating parts of the machine and theconnections between the cover and the operating-lever, the latter beingin dotted lines.

In carrying out the invention I provide the casing A of the machine witha hinged or pivoted lid or cover B, which is automatically closed by theact of starting the rotation of the basket and opened on stopping themachine. The lid or cover B is preferably pivoted on a rock-shaft 0,having at its end a tubular crank-arm D, which is connected by aconnecting-link E to the hand-lever F, used for starting and stoppingthe machine, so that on throwing over the hand-lever F to the positionshown in Figs. 1, 2, 4, and 5 to put the basket in motion the lid orcover B is swung down onto the top of the casing A, or in throwing overthe lever F to the position shown in Fig. 3 the machine-brake is appliedand the safety-cover opened.

In centrifugal machines of this class the motor employed for drivingusually consists, as shown at Fig. 4, of a Pelton Wheel G, acted on byajet of water from a nozzle H, the water being controlled by a valve orcook secured on the shaft F to which the hand-lever F is keyed, thevalve or cook being turned in its casing to open or close the passage tothe nozzle H. The inner endof the shaft F has a crank F secured to it,and a pin on said crank engages a forked portion of a weighted link I.The link I is also connected to a pin J on the brake-band J, so that theaction of throwing over the hand-lever F besides closing the water-jettightens the band J around the brake-wheel K and brings the,

machine to a standstill. Although the aforedescribed mechanism forstarting and stopping the machine has been shown on the drawings for thepurpose of illustrating the invention, it is obvious that the inventionis capable of application to machines of this class driven in adifferent manner, provided connections such as shown be made between thehand-lever F and the cover B".

Having now described the invention, what I claim, and desire to secureby Letters Patent, is-

1. In a rotary or centrifugal machine having a stationary casing thecombination with the stationary casing, of a cover adapted to close theorifice therein, and so connected to the usual starting-lever that itcloses when said lever is operated to start the machine.

2. In a rotary'or centrifugal machine, the combination with thestationary casing, of a cover adapted to close the opening in saidcasing, a rock-shaft carrying said cover, a crank-arm on said rock-shaftand a link connecting said crank and the usual startinglever,substantially as described.

In witness whereof I have-hereunto set my hand in presence of twoWitnesses.

DAVID WILLOX.
